The concept of "bog" was restricted to shrubby species and the name changed to reflect this.

Floodplain Forest Alluvial Forest The name has been changed to "alluvial forest" to
emphasize the role of active floodplain dynamics in the structure and composition of the community.

(Freshwater Tidal Swamp) as a variant of floodplain swamp.

Small isolated hammocks are recognized as variants of either mesic or hydric hammock based on their hydrology and vegetation.

Seepage Slope Wet Prairie Seepage Slope Seepage slope was re-defined as an herbaceous community within high pine and scrub communities. Some communities previously referred to as seepage slope may now fall under wet prairie if they are in a pine flatwoods system. The shrubby type of seepage slope (not due to fire suppression) would now be called shrub bog.

1990 NC Guide Name 2010 NC Guide Name Sinkhole Sinkhole Limestone Outcrop Explanation for Major Changes Exposed limestone is now classified as "limestone outcrop." This community often occurs within sinkholes.
Slope Forest Slope Forest Upland Hardwood Forest Geographically restricted to the upper Apalachicola River bluffs and ravines. Areas that were classified as slope forest outside of this range, under the 1990 Guide, should now be classified as upland hardwood forest.
Slough Slough
Strand Swamp Strand Swamp Geographically restricted to south Florida.
Swale Glades Marsh Slough Marsh Two marsh categories are recognized in place of the 1990 "swale" community. Marshes with a substrate of peat or peat/marl directly overlying limestone in the Everglades and Big Cypress region are "glades marsh." Drainageway marshes on peat overlying sand substrates in flat topography are "slough marsh."
Tidal Marsh Salt Marsh The common term "salt marsh" was chosen to avoid
potential confusion.
Tidal Swamp Mangrove Swamp Keys Tidal Rock Barren The common term "mangrove swamp" was chosen to avoid potential confusion.
Upland Glade Upland Glade
Upland Hardwood Forest Upland Hardwood Forest
Upland Mixed Forest Upland Mixed Woodland Upland Hardwood Forest Upland mixed forest is no longer included as a community in the 2009 update. Much of what was classified as upland mixed forest under the 1990 Guide will now be classified as upland hardwood forest (Dry upland hardwood forest variant),successional hardwood forest (a new altered landcover type recognized in this update), or the new upland mixed woodland community.
Upland Pine Forest Upland Pine Upland Mixed Woodland The name has been changed to upland pine so as not to imply a closed canopy. Upland mixed woodland is a new community that encompasses the ecotone between upland pine and upland hardwood forest.

Upland Mixed Woodland Upland Hardwood Forest Upland Mixed Forest Upland Pine Forest Upland mixed woodland is a new community often found in the ecotone between upland pine and upland hardwood forest. It was formerly encompassed in the descriptions of the three communities listed but differs from any of them in having an open, mixed pine-hardwood canopy and non-wiregrass understory.
